When Suzanne C. mentions Hereditary Neuropathy with liability to Pressure Palsies (HNPP) it is the opposite of CMT1A. With HNPP you have a deletion and with CMT1A there is a duplication. If interested you can review the site.

In my case I could do anything and everything until symptoms appeared in my early 50's. At that time I still was doing many many things but as CMT progressed that changed.

DNA blood testing might be in order. Here is a site where you can get information on it.

You can also telephone them.

And as Suzanne C. said we are not saying that you have it in your family but there certainly is a possibility. Can your mother run, does she trip over every little thing, are there other symptoms which she may have.

You have probably seen this site.

Also, if you overdo anything especially exercise, you can exacerbate symptoms of CMT. I have not heard that height has anything at all to do with it. I know a number of people with CMT who are not tall at all including myself.
